Flights

Items like BA 10 (Q91088347) and BA 9 (Q91089138) use this for flights with the inverse route. This doesn't match the property description and type constraint and the statements should be deleted or moved to another property. opposite of (P461) could work out instead, maybe qualified with criterion used (P1013)=inverse route (Q107587894). --- Jura 13:35, 20 July 2021 (UTC)
